The Sun Hydraulics DMDATRN636 (DMDATRN636) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve's design ensures that spools B and R are closed during the transition between positions, enhancing performance by allowing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDATRN636 operates without requiring a minimum hydraulic pressure, facilitating its use in various system configurations. It includes options for manual override controls (D, L, T types), which are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, this model employs a wet armature design wherein the working fluid surrounds the armature. This setup necessitates consideration of fluid type as some may degrade under prolonged exposure to heat from an energized coil. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to installation variances or cavity/cartridge machining errors. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). It also supports switching frequencies up to 15000 cycles/hr and features manual override requirements detailed for operational ease. This model is equipped to handle rigorous industrial applications where reliability and precision are paramount.
